CY7C1381KVE33-133AXI is an 18-Mbit synchronous flow-through SRAM with on-chip ECC, organized as 512K × 36 common I/O. It supports 133 MHz bus operation with 6.5 ns clock-to-output and a 2-1-1-1 burst access rate using an internal 2-bit burst counter (linear or interleaved). The device uses 3.135 V to 3.6 V VDD with 2.375 V to 2.625 V or 3.135 V to VDD VDDQ, and includes ZZ sleep mode and IEEE 1149.1 JTAG boundary scan.
